Stibides

Phenylstibine [58266-50-5] C H Sb, has been obtained by the reduction of phenyldiio do stihine [68972-61-2] CgH3l2Sb, (73) or phenyldichlorostibine [5035-52-9] 031130.2, (74) with lithium borohydride. It has also been prepared by the hydrolysis or methanolysis of phenylbis(trimethylsilyl)stibine [82363-95-9] C22H23Si2Sb (75). Diphenylstibine [5865-81-6] C22H22Sb, can be prepared by the interaction of diphenylchlorostibine [2629-47-2] C22H2QClSb, with either Hthium borohydride (76) or lithium aluminum hydride (77). It is also formed by hydrolysis or methanolysis of diphenyl (trimethylsilyl)stibine [69561-88-2] C H SbSi (75). Dimesitylstibine [121810-02-4] h.3.s been obtained by the protonation of lithium dimesityl stibide with trimethyl ammonium chloride (78). The x-ray crystal stmcture of this secondary stibine has also been reported. 

As the solid state structures of heterocyclic group 13 amides, phosphides and arsenides have been reviewed in the past,76 they will not be discussed here. Instead, the solid state structures of group 13 stibides and bismuthides will be described in detail. 

In contrast, the synthesis of monomeric stibides and bismuthides R2MER2 failed until we recently introduced an alternative, generally applicable pathway for the synthesis of monomeric group 13/15 compounds. We found that heterocycles may generally serve as starting compounds for the generation of their monomeric forms. In accordance with their formulation as head-to-tail adducts , strong Lewis bases are able to cleave the... 

Quite a large number of these are known and they may be prepared from the dihaloalkane and lithium dialkyl- or diphenyl-stibide in THF at low temperature, or from the sodium stibide in liquid ammonia. 

A special behavior has been shown by diphenylarsenide, diphenyl-stibide, benzeneselenate, and benzenetellurate anions. With these nucleophiles scrambling of the aromatic ring has been reported [45-48]. The reaction of /Modoanisole with benzeneselenate ions is illustrated in Sch. 6 [45]. 

Unusual organoantimony compounds have been obtained by reaction of alkali-metal derivatives of organoantimony compounds with certain organic halides e.g., compounds of the series (C6H11)2Sb—(CH2)W—Sb(C6H11)2 have been prepared from lithium di(cyclohexyl)stibide and, co-dihaloalkanes.518...
